Function-definition

Make-function-definition

Basic constructor macro for function-definition structures.

Syntax

(make-function-definition [:header <header>] 
                          [:precondition <precondition>] 
                          [:postcondition <postcondition>] 
                          [:definer <definer>])

This is the usual way to construct function-definition structures. It simply conses together a structure with the specified fields.

This macro generates a new function-definition structure from scratch. See also change-function-definition, which can "change" an existing structure, instead.

Definition

This is an ordinary make- macro introduced by fty::defprod.

Macro: make-function-definition

(defmacro make-function-definition (&rest args)
  (std::make-aggregate 'function-definition
                       args
                       '((:header)
                         (:precondition)
                         (:postcondition)
                         (:definer))
                       'make-function-definition
                       nil))
